I'm just about complete with the exhaust install on my firehawk. I couldnt wait to fire it up and listen. Heres what Ive done so far. A few weeks ago I installed coated pacesetters and a mufflex Off road Y pipe.The Y has 2 3" pipes that merge together into A 4" single out flowmaster collector. Well my car has the SLP dual dual catback which I was happy with. Until I connected the 3" catback to the 4" Y. I couldnt leave it like that. The catback looked tiny. I called %$$##* and ordered the 4" mufflex cat back with the spintec muffler. I also ordered the bmr pan hard relocation kit. Everything came in so I started the install today. I am amazed at how easy everthing has been so far. No fitment issues at all.
Before tightening everything up (headers back), I fired her up to listen and verify no adjustments are needed. All I can say is WOW!!!!! The sound and tone is amazing, no rasp, I still cant believe how awesome it sounds. I will post pics and sound clip later. For now I'm taking a break and will finish later.

 

can't wait to hear her

 

I have that kit except for the muffler. I have the Flowmaster muffler. Its a nice kit and I love the look of my V6 exhaust on roids look.

 

I love the sound of the Spintech muffler. I was very, very close to going with that setup. I choose the TPS rumbler setup only because the muffler can be changed easy and cheap. And yes it has been changed!, lol

 

sounds like you got a nice setup...get some clips and pics up asap...

 

how does the 4 inch fit under the car?

 

I want, a 1,2,3 pull WOT with power shifting OUT SIDE of the car



I really want to hear how this exhaust should sound, not just reving it up a litte

 

cant wait should be nice and deep

 

thats what she said.... ok ok im sorry

 

i recently had a 4" setup put in my car. QTP LT's, single 4" in dual 3" out spintech with a custom made cat back with no cats and an oval 3" y-pipe and the car sounds amazing. it a mix between NHRA dragster, nascar, and combat.

ive had people tell me that they hear me comng and think its an old school big block and one person told me when i was parking my car in my garage and they were inside that they though a cargo plane was buzzing the house because the way the house was shaking and hed never heard a car sound like that. i dont even listen to the radio anymore because the car is so loud but also cuz its sounds so good i took out my satellite radio and am thinking about taking out my sub too.

 

Gonna need some pictures and soundclip when you are done.
