I have a P11. I have an amg style 2.5" inlet/outlet muffler on my car now. I want to get the greddy evo. I don't like the evo canister so i wanted to use this one and just attach it to the Greddy Evo. IS it possible? Is it a lot of work?
On the Greddy Evo most of the exhaust is 2.5" but right before the canister there is about an 6"-8" bent section that measures 2.75" leading into the canister.
Anything is possible, Im sure you can do it but it will need to be done at a muffler/exhaust shop. Unless you have some really cool mandrel bending tools for big tubing, a welder and band saw.
For the price you are going to pay for the Greddy ($500+) your money would be better spent going to a custom exhaust shop and have them bend you an exahust. It will probably be cheaper for you since you already have the muffler...
Basically, you go to a custom exhaust shop....look in the yellow pages....or ask some old school hot rodders. Your looking for a exhaust system.
Look under your car, it will start after the catalytic converter, and continue on. This whole piece will come off as one unit. Basically you are going to look for the following from the shop
- Mandrel bent tubing (smooth bends, requres a special bending tool/machine)
- 2.5" diameter tubing
- The ability to coat with high temp paint to prevent rusting. (optional)
They should be able to take your stock exhaust off and pull the measurments from that and locate all the mounting thingys that are attatched. If they do not have a flange that matches the catalytic converter one they can reuse the existing one. Give them your muffler and let them know you want that on it.
What it all boils down to is the exact same thing you have on your car but in 2.5" tubing, mandrel bent, will all mounting thingys and your exhaust. There is one other component that is inline on the exhaust and youll need that...I just dont know what that is...but its there...take a look and youll see what Im talking about. You may have to leave it a day or so depending on how they operate....good luck, and dont ask me to guess the price, I have no idea.....
For the hp gain definately get the Header ($500 and less). Even the best exhaust will gain you only 3-5 hp vs 10-15 hp with a Hotshot Header. After that you can invest in some S3 cams from JWT ($550 ish), now thats cool.....
thanx dude....I'm almost done with my cosmetic modifications on my g20.
I just need some power now. I haven't touched anything int he engine yet.
For cosmetics just need rims and I'm ready to go.
YEh I figured the HS Header would give me more power. So you think I should go with the HS HEader and JWT S3 Cams first of all engine mods? (i'm not doing a turbo or det swap cuz I'm getting rid of the car in two years)
Id also get a CAI or JWT POP too. The cams are a bonus, UR pullys are nice too....I guess it just depends on how much you want to spend....and if you havent advanced your timing do so...its cheap if not free and does give it some spark!
Never mind about the timing question i read it on that link. That is a damn good link. Thanks dude. That should be posted somewhere in the engine part of the forum at the top so that people like me will just read that instead of asking mad questions. hahahahaha
Well anywyas...where can I get timing done???
Or do I do it myself?
no, the JWT POP is just a filter and adapter that allows for a smoother airflow, it replaces your stock airbox. I only have the first portion of the HS CAI from the throttle body to the MAF this piece here and just put the POP on the end of that. The full CAI extends down into the fender wheel well....
