I have the AEM CAI, about to install the comptech 4-2-1 header and have the thermal r & d axel back. I need to get a good b pipe to replace all the bottlnecks in the fatory one. What size do you recommend...2.25 in? Does anyone know a place online or someone who sells peices like this that bolt on not weld on and are less than $150? Has anyone else done this? If so, what mods did you have and did you feel any power gains? Also, I dont want my exhaust tone to change...I dont mind if it gets louder or quieter but I like that deep tone it makes! Thanks

 

decent muffler shop should do it

 

I'm kinda in the same situation myself...

Can you just order a b-pipe from a place like Apex'I?

Or know of another company that will sell only the b-pipe (specifically for a CTR)?

 

I'll probably regret this............

JC Whitney has some good quality mandrel bends in various sizes in aluminized steel. Their stainless steel bends are too 'tight' a radius for good flow.

You'll need a cooperative/intelligent muffler shop, 2 90 degree bends and 2 45 degree bends and the shop should be able to figure it out from there. Check with them ahead of time and see if they want the swaged ends or not.

You might also want to check with Dave at SMSP and save a lot of hassles.

just get the type one b pipe

 

The type one is 2.25" ID at the flanges at the cat and after the resonator and then a 1.88"ID at the axle back joint.

 

notice i said "decent" muffler shops

 

yeah that is true...

 

gotta remember Ed, us ITR_NC folks are in the heart of nascar country, those boys are serious about their straight pipes
