exhaust.. plz some canadian help!

[Pte Socks]

k.. well i went to my local shop today and i was taken aback from what ive heard. first.. no borla exhaust up here.. anyone know why? they say they dont sell well so no one carriers them.. becasue they are so expensive.. second.. im looking at a custom install.. with a universal muffler and some shop doing the rest of the exhaust... here comes my question number two.. this guy i was talking to at this place has a 2002 GP GTP and his exhaust was an engine back exhaust. He also stated for his he bought an o2 sensor for it.. any idea he would do that? because he asked me if i was gettin cat back or engine back.. i said cat and he said he got engine becasue you get way more performance.. im pretty sure cat back.. means from my catalyst converter down to my tips..and engine.. well from the engine back.. but do you know what the difference would be? like what i would need for an engine back exhaust? and this guy had Ractive tips.. and well i dont know what muffler but damn.. that car looked so nice.. damn im so beat this is so inconherent.. ill try and update this post later.. sorry..

ok.. well as i look at this i recall i missed something very big.. see.. i want to get an exhaust for my car.. the thing is.. i dont want it too loud or anything.. i just want a nice low rumble that will also give me significant (praying for 15 hp) performance increase.. i already know i will be getting a jet module from this place which is supposed to give me about 13 hp at the wheels..and i have to order a CAI online and get them to install it for another possibly 8-10 hp at the wheels and i need an exhaust that LASTS for my car.. the reason why i was so hooked on borla was becasue it was completely stainless steel which lasts for so long compared to everythign else.. i realise that from this shop i can get a stainless muffler with exhaust tips ( im thinking the ractive ones this guy has.. they arent big or anything but they look nice.. and are said to give excellent performance.) i will also have to get a shop around here to build me the rest of the setup.. im asking what gain i would get over an engine back exhaust compared to just a cat back exhaust.. and what i would need extra to get a full engine back exhaust.. sorry.. but ive never heard that term before and im kinda curious about it because this guy said you will notice a much larger gain out of an engine compared to cat back.. so hopefully someone can answer some of my questions...i would really appreaciate it

[Pte Socks]

does anyone know about engine back exhausts?

[MJE95GAGT]

What he means by "engine back" is piping from the downpipe back, no resonator and no cat (he might even had no mufflers and just had straight piping) You will lose some low-end but will gain mad top-end

[Pte Socks]

when you mean high end.. what do you mean? higher rpm's? and what do you mean by mad... like 20 hp? and i heard this guys car.. im im sure he had a muffler

[Themeneea]

high end is high RPM's, but theres is no way you will pass emissions without a cat

[MJE95GAGT]

I mean like once you get to higher rpms (4-6K) you will feel a greater pull and more power. 20hp is pretty optimistic for any exhaust. With an "engine back" with say 2.5" mandrel piping, its pretty safe to say you will get 15hp at the crank tho

[BBT]

To me, engine back means everything from the engine block itself. That means headers (virtually impossible to find for GA engines), mandrel bent pipes, hi-flow cat , performance muffler & tips.

Cat-back means exactly as you state, new hardware from cat to tips.

I would take with a BIG grain of salt any HP claims anybody makes for any setup, unless they can show you verifiable dyno sheets. And even then, who knows what else they may have done to the car to get those numbers?

I'd do it for your own satisfaction. If ya get the numbers ya hope for, great, but if not, you have a system in place that looks and sounds the way YOU want.

[Pte Socks]

well then i think ill be gettin a cat back exhaust with perhaps a new catalyst converter to help it all out.. i just wasnt sure if i could get like 20 hp with an engine back or stick with a cat back and get about 10 hp at the wheels.. but from what you guys are saying.. i think ill stick with the cat

Try contacting Mopac for parts. They are Western Canada's largest Borla dealer so they will be able to get anything you want at probably the best prices. I bought my Borla Turbo muffler for $139 CDN. That's about the same as the US posted price on the Borla website.

master.. wha who? omg you are a godsent! holy god that place sells lots of performance parts for my car! omg! could you have found me my store where i can buy all the parts i want for my car! omg.. i totally have to thank you so much man! theres even a store in edmonton and only a 25 minute drive away from my house! omg.. that is so firggin sweet! im so going there tomorrow and asking them all kinds of questions! omg thank you thank you thank you.. you are a god..

You can order the Borla cat-back from Canadian Tire... It's approx $1200 CDN. :)

[Pte Socks]

yea.. but 1200 bucks is expensive as hell.. i was hoping on only paying about 900 for an exhaust.. and im pretty srue i can get that by not going through crappy tire..

[master]

Canadian Tire is cheap for most parts because they sell CHEAP parts. If you order good stuff like Borlas and K&N and good stuff like that, they aren't that cheap because everything is custom order and charge shipping and handling. You're better oof going to a pro shop like Mopac because they buy performance parts in bulk and get great prices.

FYI. powerslots for the 99+ GA and Aleros are $129 CDN each at Mopac.

[Pte Socks]

uhh call me a moron.. but what is a powerslot and what does it do? im thinking for an exhaust ill go to that mopac place.. ill get the borla muffler with tips and for the rest.. well here where i hit a problem.... i would most likey get custom piping at some shop.. but im wondering.. what will a new cat. converter do for my car hp wise? like.. basically i will be getting a CAI, a Jet Chip module, and a borla cat back exhaust.. im wondering if gettin a new cat. converter will help out much in terms of gettin more hp.. like if its only going to give me 2 or 3 hp then i will say forget it.. but if it gives me an additional say 5-7 hp with these other mods.. ill definatly think about it.. im wondering because im looking at performance upgrades.. i know the jet chip module will give me about 13 hp at the wheels.. with the CAI giving me perhaps 8 or so.. and the exhaust another 10 or so.. giving a total of 30 additional hp to my car making it about 200 hp.. im wondering if its worth gettin a new catylist converter and perhaps giving me another 5 to 7 hp on top of the 200... any ideas? and do you know if the hp ratings for each mod are pretty accurate?

[master]

Unless you're going with forced induction (supercharging or turbocharging) they stay with the stock cat. It flows more than enough for a 3.4L V6.

[Pte Socks]

thx.. any idea if my estimates for hp gains are correct?

[c3hp0]

Newbie here. Greetings to all.

I have had exhaust work done locally - at Atlas Muffler on 99st and 51ave - on my 2000 Regal GS. Haven't considered the wife's Alero, yet.

The downpipe was done (braided ss flex) and I had some restrictrions removed after the cat (u-bend & resonator) - all replaced with 3" pipe. I'm considering replacing the rest of the exhaust and the stock muffler & tips.

The sound only ended up being a bit more rumbly - increased lower frequency (VLF nearly) only.

Atlas does good work. Ask for Kevin (one of the owners, BTW).

Cheers.

thx man.. so atlas on 99 and 51st ave does custom exhausts.. well i know ill be getting 2.25 inch piping.. i guess any larger than that and ill end up losing torque... and as for mandrel or straight piping.. well i guess ill just have to see what fits for my car.. thx for the help man.. though.. i have one really stupid question .. im not 100% sure about this.. but doesnt mandrel bent piping mean that the interior size of the pipe does not diminish at the bends? i was just kinda curious..

[MJE95GAGT]

yup 2.25" mandrel means the piping will stay the same throughout the whole exhaust and thru the bends, with crimp bent it can get to as thin as 1.5" on the bends

[Pte Socks]

thats exactly what i thought.. i just wanted to be 100% sure about that so if i cant get straigh piping ill go with mandrel bent
